Space Environment Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water. In our solar system, the four gas giants are Jupiter, Saturn, Neptune, and Uranus. Planets with their relative sizes to scale. The tiny bluish dot at the lower left is Earth.

What is the physical difference between a star and a planet?  (Intermediate) Stars do this; planets don't. In order to have high enough temperatures in the core to burn hydrogen, an object needs to have a mass of at least 75 or so times that of Jupiter. Anything more massive than that is automatically considered a star. (ii) The way they form. Stars form when a cloud of gas, out in a nebula or other region of interstellar space, collapses under the influence of gravity. Planets, on the other hand, form when material in the disk around a pre-existing star begins to condense around rock/ice cores.

- Excellent question! The planets in our solar system are each made out of different things. The inner planets (Mercury, Venus, Earth, and Mars) are relatively small rocky planets made up mostly of silicate minerals and iron and nickel metal. Most of the earth is made up of only three elements: iron, silicon, and oxygen.

solar system According to the law of periods, the cube of the average ... of a planet from the sun is always proportional to the square of the period. Because they are mostly made up of gas. They also are very low in density. They have a larger mass than any of the inner planets. They were formed in a colder region of the star nebula, and are further away from the sun therefore, they have held onto their less dense gases.

Learning About Our Solar System The celestial bodies in our Solar System are divided into different sections: the inner planets of Mercury, Venus, Earth and Mars separated by the asteroid belt from the outer planets of Jupiter, Saturn, Uranus and Neptune. Each celestial body is made of a different type of material: rock, gas or ice. slide 1 of 4.The celestial bodies in our Solar System are divided into two regions, based on the structure and size of the planets. The first region of the Solar System is commonly referred to as the inner planetary area, containing the first four planets, which are rocky worlds.ypes of Celestial Bodies. According to the accepted modern theory, the objects in the Solar System are segmented into three distinct classifications: planets, dwarf planets and other small bodies. Each of these are defined by the International Astronomical Union.

Difference between Stars and Planets The sun being the closet star of the earth, the bright light of sun make other stars invisible during day time. The bodies which revolve around the sun in a certain orbit are called planets. There are following eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Planets vs Stars.

- All the elements on Earth were formed in the heart of exploding stars. The early Universe was made of just two elements, hydrogen and helium, which formed into stars. At the fiery core of these stars, the hydrogen and helium were forced together to form new, heavier elements. Even heavier elements were created in the explosions of massive stars, called supernovas.

Our Solar System The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas. This is an important question, and one that is difficult for scientists to understand.

Space Environment What are stars made of? Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb. Even though it is constantly exploding in a nuclear reaction, the Sun and other stars are so large and have so much matter in them that it will take billions of years for the explosion to use all the fuel in the star.

What Is a Star? A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. Nuclear fusion reactions in its core support the star against gravity and produce photons and heat, as well as small amounts of heavier elements. The Sun is the closest star to Earth.

Do I Know This ? View full size image. Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). But the stars are very, very far away from our solar system so they appear to be very tiny to us, even though up close they are large. The planets are much closer, inside our solar system. Although the planets are much smaller than the stars, planets appear to be about the same size as the stars because they are so close to us. Planets don't produce their own light. They reflect the light of the sun in the same way our moon reflects sunlight.

Planets and How They Formed All the rest would have vaoprized. So the inner solar system objects are made of iron, silicon, magnesium, sulfer, aluminum, calcium and nickel. Many of these were present in compounds with oxygen. There were relatively few elements of any other kind in a solid state to form the inner planets.

What is the Milky Way Galaxy made of? Obviously the milky way galaxy is made up of billions of stars and also dust and gas. Solar systems are also present especially ours lies 30000 light years away from the galactic centre.Also the stars are small and tightly clustered, making it look cloudy and milky.

What is a planet? Credit: NASA/ESA/Hubble Heritage Team (STScI/AURA). The planets in our solar system didn’t appear out of nowhere. Neither did the sun. They were all part of a big cloud of gas and dust.Gravity collected lots of material in the center to create the sun. The left over stuff swirled around the forming sun, colliding and collecting together. Some would have enough gravity to attract even more gas and dust, eventually forming planets.ost of the time these clouds form a type of star called a brown dwarf. They are pretty big compared to most planets, but they are not big enough to turn into the kind of star that makes lots of energy and gives off light. Relative sizes of different planets, our sun, and things in between.

Star Birth Stellar Building Blocks. Stars form from the simplest of building blocks - huge clouds of gas and dust that permeate the Galaxy. It's hard to believe, but everything in our Solar System, from the Sun to the planets, ocean, plants and us, was once a cloud of gas and dust spread out over a large area of space.

What are planets made of? Venus is made up of nickel and iron in its interiors but it has not been proved yet and the gas present on the Venus is carbon dioxide. Earth is composed of iron. And nearly 30% of it is found in its core. Earth also has 30% of oxygen and 14% of magnesium. Mars also comprises of iron like the other three planets. With the iron it has 16% of sulfur present in its core and silicate mantle. It is speculated that the largest planet in solar system i.e. Jupiter is made up of rocky core and the main bulk of Jupiter consists liquid metallic hydrogen.
